Sturdy and Easy to Move
Color: Black, Size: 132"- 6 Panel
This 6 ft black partition on wheels is exactly what I needed to divide space without sacrificing style or stability. It’s sleek, professional-looking, and blends in well with any environment—from office spaces to home studios. The build quality is impressive—very sturdy and doesn’t wobble at all once it’s in place. The wheels glide smoothly and lock securely, making it easy to reposition or keep stationary as needed. Assembly was quick and straightforward, with all parts clearly labeled. Overall, this partition is a perfect combination of functionality and design. Highly recommend it if you need a durable, mobile room divider that looks great and performs even better.

Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!
